"OpenStrip" is a free, Open-Source reimplementation of the Control Strip.
What's new in version 0.4
strip now clings to the sides of the screen
strip can now be made to face either left or right
added new "Loadometer" module, graphs processor load under OS X
added an "Experimental" folder, containing monitor module projects by Ian Ollmann
added a built-in "OpenStrip Controls" module, currently containing just a Quit command; this will allow us to make OpenStrip a faceless background app, and still provide access to Quit, About, Preferences, etc.
